With more and more modules coming on the market and the variables allowed, it's going to turn out that more and more automatic testing is surely going to be mandated. After all, Google is doing millions of daily automatic tests.

The virtualized infrastructure as noted is much more complex and the challenges are there to move through. Fortunately there's now a useable and probably cost effective way to test. And eliminating some redundancy of those test may eventually save even more time and money in the process.

How true, things don't go as smoothly as planned or hoped. The interop testing is going to be wildly useful as the NIP Agengy moves forward. I couldn't help myself observing the sign in the background made me think of a CIA or other spy agency logo.

That's a great point. Coming from the world of enterprise software, it reminded me of what happens when you don't conduct interoperability -- as we saw in healthcare IT. So glad to see service providers and developers conducting interop tests although it's a shame that apparently so many SPs repeat the same tests on the same products.

This reminds me a lot of IMS, and all the interoperability testing that was necessary for IMS to work. IMS in a sense was the first step in NFV, where various function previously within monolithic mobile switching centers became distributed elements that could come from various "best of breed" vendors.

EPC NFV Interoperability testing is certainly as crucial as interop testing was for IMS.
